How does it's rotational resistance change? I thought it's basically an electric can motor being turned by the engine, so the resistance to passing the coils of wire through a magnetic field would be constant whether the there was demand for the electricity produced or not??


I don't completely understand what goes on in there either.. BUT I do know that it takes more energy of one type to make more energy of another type. I just always understood it took more fuel to make 80amps than it did to make 5 amps..
Since it is done with magnetic force maybe as the amps get higher so does the magnetic force, causing the alternator use more HP to turn it????
